A stacked UFC 148 card in Las Vegas just got another jolt of star power today, as UFC President Dana White announced that due to scheduling conflicts with the United Nations Conference on Sustainable Development on June 20-22, the June 23rd rematch between middleweight championAnderson Silva and number one contender Chael Sonnen has been moved from Havelange Stadium in Rio de Janeiro to the MGM Grand Garden Arena for the July 7th event in the fight capital of the world.

White made the announcement Tuesday morning at a press conference in Rio with both Silva and Sonnen both in attendance.

It was also confirmed that the July 7th event would feature the title-fight rubber match between bantamweight champion Dominick Cruz and rival Urijah Faber. Faber defeated Cruz via first-round submission to retain the featherweight title in Cruz' first bout in the WEC in 2007. Cruz went on to win the bantamweight championship in the WEC and became the UFC's first 135-pound title-holder. In a 2011 rematch, Cruz won a unanimous decision.
